Home Rule in New York: The Need for a Change

This article is intended to provide a practical lens into how Home Rule issues unfold in complex matters involving the City, and to suggest how a much-needed Home Rule constitutional amendment could re-shape or, at the very least, clarify Home Rule standards. Section II will provide some historical and legal background on Home Rule; Section III will analyze some of the more well-known Home Rule cases that the Law Department litigated during the Bloomberg Administration; and Section IV will discuss insights gleaned with respect to, and will offer several recommendations for, the future of Home Rule in New York

Proper-time relativistic dynamics

Proper-time relativistic single-particle classical Hamiltonian mechanics is formulated using a transformation from observer time to system proper time which is a canonical contact transformation on extended phase space. It is shown that interaction induces a change in the symmetry structure of the system which can be analyzed in terms of a Lie-isotopic deformation of the algebra of observables

Global (in Time) Solutions to the 3D-Navier-Stokes Equations on R^3

A well-known unsolved problem (in the classical theory of fluid mechanics) is to identify a set of initial velocities, which may depend on the viscosity, the body forces and possibly the boundary of the fluid that will allow global in time solutions to the three-dimensional Navier-Stokes equations. (These equations describe the time evolution of the fluid velocity and pressure of an incompressible viscous homogeneous Newtonian fluid in terms of a given initial velocity and given external body forces.) A related problem is to provide conditions under which we can be assured that the numerical approximation of these equations, used in a variety of fields from weather prediction to submarine design, have only one solution. In earlier papers, we solved this problem for a bounded domain. In this paper, we use an approach based on additional physical insight, that allows us to prove that there exists unique global in time solutions to the Navier-Stokes equations on R^3

Everything’s Bigger in Texas: Examining the Mandatory (and Additional) Financial Burden of Postsecondary Education

Student fees remain an under-researched aspect of postsecondary education and finance (Kelchen, 2016). This study examines the mandatory and additional fees charged to full-time, in-state undergraduate students by public and private not-for-profit four-year institutions in Texas (n=96). Findings demonstrate the average four-year institution in Texas charges over $1,500 per academic year in mandatory fees,$500 higher than the national average. Moreover, private institutions charge an average of $1,100 less than publics, while fees comprise 6.8% of the total cost of attendance at private and 29.1% at publics. Institutions of higher education compose fee explanations above the 12th-grade reading level and only 5.2% of the sample provided fee explanations in a language other than English, thus further marginalizing non-English speaking language populations in Texas. Implications for policy makers, practitioners, and future research are addressed.Educatio

Implementation of a point-of-care ultrasound skills practicum for hospitalists

Introduction Point-of-care ultrasound is recognized as a safe and valuable diagnostic tool for patient evaluation. Hospitalists are prime candidates for advancing the point-of-care ultrasound field given their crucial role in inpatient medicine. Despite this, there is a notable lack of evidence-based ultrasound training for hospitalists. Most research focuses on diagnostic accuracy rather than the training required to achieve it. This study aims to improve hospitalists' point-of-care ultrasound knowledge and skills through a hands-on skills practicum. Methods Four skill practicums were conducted with pre-course, post-course, and six-month evaluations and knowledge assessments. Results The mean pre- vs. post-course knowledge assessment scores significantly improved, 41.7% vs. 75.9% (SD 16.1% and 12.7%, respectively, p < 0.0001). The mean ultrasound skills confidence ratings on a 10-point Likert scale significantly increased post-course (2.60 ± 1.66 vs. 6.33 ± 1.63, p < 0.0001), but decreased at six months (6.33 ± 1.63 vs. 4.10 ± 2.22, p < 0.0001). The greatest limitations to usage pre-course and at six months were knowledge/skills and lack of machine access. While knowledge/skills decreased from pre-course (82.0%) as compared to six-months (64.3%), lack of machine access increased from pre-course (15.8%) to six-months (28.6%) (p = 0.28). Conclusion Hospitalists agree that point-of-care ultrasound has utility in the diagnostic and therapeutic management of patients, though the lack of training is a significant limitation. Our study demonstrated that a brief skills practicum significantly improves hospitalists’ confidence and knowledge regarding ultrasound image acquisition and interpretation in the short term. Long-term confidence and usage wanes, which appears to be due to the lack of machine access
